Self Drilling Screw, Hwh Unslotted W/ Bonded Washer(Neo), Zinc Cr+3 (Inch)
Hex Washer Head (HWH) Unslotted Self-Drilling Screws with a Bonded Washer (Neo) and Zinc Cr+3 finish are designed to drill, tap, and fasten in one operation while providing a watertight seal. The bonded washer combines a metal washer with a rubber neoprene backing to prevent moisture intrusion and improve load distribution. Zinc Cr+3 plating offers moderate corrosion resistance.
These screws are ideal for roofing, siding, metal panels, HVAC systems, and other applications requiring efficient fastening with sealing protection. The hex washer head provides strong torque transfer, while the unslotted design ensures a clean installation surface. The bonded neoprene washer reduces vibration, seals against water, and distributes pressure evenly. Zinc Cr+3 coating protects against rust in indoor and light-duty outdoor environments. Self-Drilling Screws with HWH Unslotted Bonded Washers deliver reliable fastening, sealing, and long-term performance in industrial and commercial projects.
